Introduction
The M2C active antenna combiner is designed as an ide-
al matching component to Lectrosonics digital transmit-
ters. Up to eight transmitters can feed a single antenna
to minimize cabling in multi-channel systems. The inputs
are isolated to minimize crosstalk and IM (intermodula-
tion) between RF channels.
The overall architecture of the design provides excel-
lent performance with low power consumption and heat
buildup. Front panel indicators display active status of
RF inputs. A USB port on the front panel is provided for
rmware updates.

M2C Combiner Block Diagram
Up to 100mW can be delivered to each input port with-
out generating IM (intermodulation) signals due to the
use of high overload components. Input signals above
50mW are attenuated automatically to maintain the
50mW maximum output. Front panel LEDs indicate the
operating status and various fault modes.
Three cooling fans are employed to maintain the oper-
ating temperature. One fan is dedicated to the output
amplier and runs all the time. Two variable speed fans
are mounted on the rear panel to exhaust heat from the
interior of the chassis.

IEM/IFB Transmitters
Lectrosonics M2T IEM/IFB Transmitter
Up to eight transmitters can be connected to the M2C
on frequencies from 470.100 to 614.375 MHz. The
combiner mixes the incoming RF signals and delivers
the mix to the nal amplier. The maximum RF output
power is 50mW.
The combiner applies maximum attenuation to each
input channel until an RF signal is present at +5dBm or
greater. Once the input channel is “active,” the sig-
nal power is monitored and attenuation is applied as
needed. If the signal is greater than +17dBm (50mW),
the attenuator will reduce it to +17dBm.
When the transmitters are placed close to the combiner,
the type of coaxial cable is not critical, but low loss 50
ohm cable is recommended. At longer cable runs, low
loss cable is more important.
If the transmitters are greater than 50mW, cable loss
is generally not a concern, unless the loss is consider-
able and the resulting signal entering the combiner is
less than 50mW. The combiner does not apply gain to
increase the incoming RF signal level.

Setup and Operation
Installation
The M2C antenna combiner can be installed in a 19
inch rack with other devices directly above and below
it. Adequate ventilation in normal conditions is provided
by the front and side panel vent openings and the rear
panel fans. If another device that generates excessive
heat is mounted below this combiner, it is possible that
the internal temperature could reach a high enough
point to cause the combiner to shut down. If this hap-
pens, the front panel LEDs will indicate the condition as
described under LED Indicators.
Setup
1) Turn the power switch o and then connect the
AC power to the mains outlet and the combiner.
2) Connect the output antenna to the rear panel jack.
3) Connect the coaxial cables from the transmitters
to the input jacks on the rear of the combiner.
4) Turn the power on and observe the front panel
LEDs.
5) The LED for each input channel will indicate the
status as described under LED Indicators.
LED Indicators
Front panel LEDs glow and blink dierent colors to indi-
cate various operating modes and fault conditions.
Operating Modes:
Green
Channel active
Normal operation
Yellow
Channel active
w/ attenuation
Red
Out of band signal
Full attenuation
LED O
No signal
Full attenuation
If a channel LED is o, it means there is no usable signal
present and the attenuator will be at the maximum level
(30 dB down) to suppress potential noise. When no
channels are active, the RF amplier is turned o.
Each channel will become active and the associated
LED will glow green when an RF signal at +5dBm (3.16
mW) or greater is present. If the signal is greater than
+17dBm (50 mW) the channel will be active, but the
attenuator will reduce the signal to +17dBm and the
channel LED will glow yellow.
If the incoming signal is out of the frequency band of the
combiner, the channel LED will glow red and full attenu-
ation will be applied.
Fan Operation Fault:
If one of the fans stops turning, all front panel LEDs with
blink yellow.
High Temperature Warning:
If the internal temperature rises to 80°C (176°F) the front
panel LEDs will blink red, alternating with the operating
mode indications.
High Temperature Shutdown:
If the internal temperature reaches 85°C (185°F) the RF
ampliers will be turned o and the front panel LEDs will
blink red rapidly. When the combiner is in this state, the
power must be turned o and the unit allowed to cool
before powering up again.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting
cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop at-
tempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection,
send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the
factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are
no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
at rate plus parts and shipping. Since it takes almost as much time and eort to determine what is wrong as it does to
make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for
out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without rst contacting us by email or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly
shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed”
for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
